Steg MGL3 - 3.5" Wideband Speaker

       The Steg MGL3 is a compact 3.5 inch wideband driver engineered for active car audio systems where space is limited but performance is still a priority. Whether you’re upgrading factory 3.5 inch dash speakers or integrating into a custom front stage, the MGL3 delivers detailed and efficient wideband performance in a highly compact form.

       Featuring a specially treated metal cone, high-grade neodymium motor, and a 1 inch high-efficiency voice coil, the MGL3 is built for smooth, extended frequency response from 145 Hz to 15 kHz. It offers excellent sensitivity (87 dB @ 2.83V/1M) and transient response, making it ideal for reproducing midrange and upper-frequency content with clarity and control.

       The vented die-cast aluminum chassis adds rigidity while improving thermal handling and airflow, and the CNC-finished motor structure ensures long-term reliability and consistent performance. With a mounting depth of just 40 mm and a small 73 mm installation diameter, the MGL3 is a perfect fit for tight OEM locations or space-conscious custom builds.

       The Steg MGL3 offers a refined solution for those who want wideband response and strong midrange clarity without the footprint of larger drivers—making it a top choice for both OEM integration and high-end compact system designs.

"Using these for rear fill and couldn’t be happier. Mated these up to a Helix V12 and these Stegs perform very well, couldn’t be happier. They look awesome too!"
